    I just looked at average winter low temps for your area...+40˚. You could probably rewire the defrost control to cycle off the compressor instead of the fan, and let it "air" defrost. :grin2:

    Just about every mfg but Rheem. I ran across an internet-purchased brand (I'd never heard of) recently that energized in heat, but don't know of any other resi equipment brands with the atypical...

    Best way to accomplish that is convert the defrost control to a "demand" type. Not sure Goodman has something you could just swap out with. The higher SEER units may come with demand controls that...

    Low suction and low/non-existent superheat is airflow related. Not enough heat available to boil off the refrigerant. If it's intermittent, I'd guess a funky blower motor control. That or something...

    Can't tell for sure, from all your posted info, but a low to normal superheat, with the 50 psi suction pressure, is symptomatic of low airflow, and would suggest the TXV is attempting to do it's...

    Why 1940 cfm for a 3 ton condenser? and how? :confused:

    I'm thinking erratic airflow rather than TXV problems.

    The "normal" suction pressure for the ID/OD temps would probably be around 80 psi. You're at 60 (35˚ saturated)...once the sun goes down and the temps drop, so will the suction pressure. It's...

    If the motor is running, there must be some voltage, on one of the motor leads, coming from some where, whether or not there's a "call" for fan.

    Use a clamp-amp meter to determine which lead(s) is...

    The tube you're referring to is the equalizer line for the TXV, providing the necessary evaporator pressure to the valve, for it to work as designed. Since the system does well in cool cycle, there...

    Those older Goodman "sequencer" type blower controls are notorious for intermittent failures to "close" on a stat call. Quite likely the cause of the occasional freeze ups.

    A problem with the TXV or RV won't generate those pressures, with a "normal" refrigerant charge. Recover refrigerant until the system will run without tripping HP limit, then try to do some analysis.

    The condensing temp is about equal to ambient. Normal charge with a TXV issue would have higher head pressure than what you measured.

    Mufflers are always (all I ever saw) in the hot gas line at the compressor.

    The pressures, cool liquid/suction lines and "frosting" points suggest a liquid restriction and too much charge. Of...

    OD + 50˚ SCT isn't normal for anything residential to my knowledge. OD + 20˚ is about normal for 13 SEER stuff.
